Phenotypic and genotypic evaluation of synthetic hexaploid wheat lines (AABBDD) for grain parameters under the conditions of Western Siberia

Wheat is both a vital food crop and an economically important commodity for Russia. Plant breeders are increasingly looking to wild relatives to introduce new genes and alleles to obtain high, stable wheat yields. In this paper, we present the study results for grain morphometric parameters and genotyping with usage of 47 SNP (single nucleotide polymorphisms), including 13 markers assosiated with genes responsible for grain size/weight. For the first time in Western Siberia these data were obtained for synthetic hexaploid wheat genotypes set (the genome AABBDD) in which the genome D was transferred from Aegilops tauschii , originated from regions with the highest genetic diversity of this species. The evaluation of 47 synthetic hexaploid wheat lines was performed on the experimental field of Omsk SAU (Omsk city) in 2016-2018. The synthetic lines were created in CIMMYT by crossing durum wheat ( Triticum durum Desf., АВ genome) with different entries of Aegilops tauschii Coss...
